According to the surface of the galvanized steel coil, the types of spangles can be distinguished. Whether it is large, regular, minimal or zero spangles depends on the substrate used for hot dip galvanizing.
Application of large spangle galvanized steel coil:
1. Construction: Roofs, Walls, Garages, Acoustic Walls, Plumbing, Prefab and Modular Homes, Solar Panel Cable Management Systems, Drywall Zoning Systems, Roofing and Cladding, HVAC – Plumbing and Refrigeration, Electrical Lighting, etc.
2. Automobiles and accessories: mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes, truck bodies, car wheels, etc.
3. Household appliances: refrigerator back panel, gas stove, air conditioner, electronic microwave oven, LCD display frame, CRT explosion-proof belt, LED backlight, electrical cabinet, water heater, furniture, etc.
4. Agricultural use: pig house, chicken house, granary, greenhouse pipeline, etc.
5. Others: heat shields, heat exchangers, dryers, water heaters, pre-galvanized ERW pipes, compressor shells, rail car parts, wheel rims, railway wagons, etc.

In the construction field, due to its excellent corrosion resistance and molding properties, it is widely used in the production of building components such as roofs, walls, and floors, as well as the manufacturing of metal products such as ventilation ducts and water tanks.
In the field of transportation, due to its excellent corrosion resistance and molding properties, it is widely used in the manufacture of automobile parts such as car casings, compartments, and doors. It can also be used in the manufacture of lightweight metal products such as bicycle frames and motorcycle frames.
It is also widely used in the manufacturing process of the electronic field.
